US Congress widens Nvidia probe, seeking testimony from Jensen Huang and Trump officials

US Congress has expanded its investigation into Nvidia, requesting testimony from chief executive Jensen Huang and officials connected to the Trump administration, according to the South China Morning Post. The transmission channel runs through regulatory and policy risk: a widening probe raises the prospect of legal exposure, potential remedies, or constraints on Nvidia's business, which investors typically price as a higher risk premium on the equity rather than as a change in near-term earnings. Nvidia (NVDA) is the most directly exposed asset, given its outsized weighting in semiconductor and AI-focused indices and the sensitivity of its valuation to growth assumptions tied to data-center demand. Secondary exposure extends to other large-cap chip and AI-linked names, where any read-across from regulatory scrutiny of a sector leader can shift sentiment. The next catalyst to watch is whether the requested testimony is formally scheduled and what documents or subpoenas accompany it, as concrete procedural steps would give traders a clearer basis for assessing the scope of potential consequences.

HIGH-impact news is typically a market-moving event with multi-pip or multi-percent intraday reactions. Examples include central bank rate decisions, major CPI/NFP releases, geopolitical shocks, mega-cap earnings beats/misses, and regulatory announcements. Traders typically position-reduce or hedge ahead of scheduled HIGH-impact events, and follow the wire in real time to react to unscheduled ones (war headlines, central-bank emergency statements, surprise corporate actions). The Trading News Terminal squawk box reads every HIGH-impact headline aloud the moment it hits the wire — so active traders don't have to stare at the feed.

Active traders typically follow a three-step workflow when a market-moving headline hits the wire: (1) read the headline on the terminal or hear it on the squawk box; (2) assess whether the news is already priced in (by checking intraday price action in the seconds before) or whether it's genuinely new information; (3) act — either entering a breakout position, fading an overreaction, or tightening stops on existing trades. Trading News Terminal's Pro plan delivers wire-grade headlines within seconds of the source, with automatic audio squawk on every HIGH-impact event, so the read-assess-act cycle never waits on a refresh button.
